外星探测器11月“攻击”地球？哈佛教授详解6大“异常”

Core Viewpoint - The article discusses the discovery of the interstellar object 3I/ATLAS, which has sparked debates regarding its nature, with some scientists suggesting it could be an alien probe disguised as a comet, while others maintain it is a typical interstellar comet [1][3][23]. Group 1: Discovery and Characteristics - 3I/ATLAS was discovered on July 1, 2025, by the ATLAS telescope in Chile, marking it as the third confirmed interstellar visitor to the solar system [5]. - The object is estimated to have a diameter of 10 to 20 kilometers, with some estimates suggesting it could be as large as 40 kilometers [6]. - Its trajectory is characterized by a high eccentricity of approximately 6.2, indicating it is on a hyperbolic path, which is atypical for solar system bodies [5]. Group 2: Anomalies and Theories - Avi Loeb, a Harvard professor, proposed six anomalies regarding 3I/ATLAS that challenge traditional comet models, suggesting it might be an alien spacecraft [13][19]. - The anomalies include its large size and brightness, the absence of cometary gas features, an unusual orbital path, and the timing of its closest approach to the Sun [13][15][16][18]. - Loeb emphasizes the need for the scientific community to consider all possibilities regarding the object's nature, rather than hastily categorizing it [23]. Group 3: Scientific Community Response - The mainstream scientific community, represented by researchers like Darryl Seligman, largely views 3I/ATLAS as a comet, citing observed cometary activity and characteristics [21][22]. - Seligman argues that the initial size estimates were based on assumptions of inactivity, and that further observations may reveal more about its gaseous emissions [22]. - The debate highlights the importance of open-mindedness in scientific inquiry, with calls for improved observational capabilities to study such interstellar objects [24].
